Abstract (en)

[origin: EP0189894A2] Disclosed are basic circuits operable in a current mode in multivalued logic circuit systems, analog circuit systems and the like. Examples of the basic circuits are a successor, quantizer, adder, subtracter, divider, multiplier, decoder, literal circuit, equivalence circuit, bilateral T-gate, complement literal circuit and h operator circuit. These basic circuits are realized by using floating threshold switching circuits, floating window switching circuits, threshold SPDT switching circuits, and the like.
